1 Claim. (Cl. 119-48) The present invention relates to new and usefulimprovements in cow barn gutter grates and has for its primary object toprovide, in a manner as hereinafter set forth, novel means forpositively preventing the animals from standing with their hind feet inthe gutter and thus becoming contaminated.

Another very important object of the invention is to provide a grate ofthe aforementioned character which may be expeditiously adjusted forinstallation in gutters of various widths.

Other objects of the invention are to provide an adjustable gutter grateof the character described which will be comparatively simple inconstruction, strong, durable, compact and which may be manufactured atlow cost.

These together with other objects and advantages which will becomesubsequently apparent reside in the details of construction andoperation as more fully hereinafter described and claimed, referencebeing had to the accompanying drawing forming a part hereof, whereinlike numerals refer to like parts throughout, and in which:

Figure 1 is a perspective view of a gutter grate embodying the presentinvention, showing the device installed;

Figure 2 is a vertical sectional view through one end portion of thedevice, taken substantially on the line 22 of Figure l and drawn to anenlarged scale;

Figure 3 is a fragmentary view in transverse section through anintermediate portion of the device, taken substantially on the line 33of Figure 1 and drawn to an enlarged scale; and t Figure 4 is afragmentary view in longitudinal section through the other end portionof the device, taken substantially on the line 4-4 of Figure 1 and drawnto an enlarged scale.

Referring now to the drawing in detail, it will be seen that theembodiment of the invention which has been illustrated comprises anelongated frame of suitable metal which is designated generally byreference character 5. The frame 5, which may also be of any desireddimensions, includes a pair of longitudinal side bars 6, 6a of angleiron which are terminally connected by telescopically adjustable tubulartransverse end bars 7, 7a. The tubular end bars 7, 7a of the frame 5comprise male and female members or sections 8 and 9, 8a, 9a,respectively, which are secured in adjusted position through the mediumof setscrews 10, 10a threadedly mounted in said numbers 9, 9a.

Mounted in the frame 5 and fixed to the bar 6 are laterally spacedtransverse angle iron grate bars 11, 11a, 11b, 11c, 11d, lie withslidably overlying transverse angle iron grate bars 111, 11g, 11th,111', lllj, 11k laterally spaced in the frame 5 and fixed to the bar 6a,all of said bars being adapted to traverse the gutter.

It is thought that the use of the device will be readily apparent from aconsideration of the foregoing. Briefly, reference character 12designates the usual gutter in the floor 13 of a cow stall or barn. Toinstall the grate, the setscrews 10, Illa are loosened and the angleiron bars 6, 6a are seated on the upper corner portions 14,-14a of thegutter 12. To accomplish this the frame 5 is adjusted as to Width byslidable adjustment of the end bars 7, 7(rand of the grate bars 11 to Heand 11 to 11k relatively. The setscrews 10, lila are then tightened forsecuring the adjustment. The grate bars 11 to 112 and 11 to 11k are ofinverted V-shape in cross section to discourage cows from standingthereon and are spaced apart sufiiciently close together so as not toinjure the hoofs of cows or permit the hoofs to pass between said bars.Of course, the lapped inner end portions of the bars 11 permitadjustment of the frame 5.

The foregoing is considered as illustrative only of the principles ofthe invention. Further, since numerous modifications and changes willreadily occur to those skilled in the art, it is not desired to limitthe invention to the exact construction and operation shown anddescribed, and accordingly, all suitable modifications and equivalentsmay be resorted to, falling within the scope of the invention asclaimed.

What is claimed as new is as follows:

A cow barn gutter grate comprising a frame including a pair of angleiron side bars adapted to receive the upper corners of a gutter, a pairof telescopic end bars terminally connecting said side bars andproviding for lateral adjustment of said side bars relatively to varythe Width of the frame, and angle iron grate bars extending inwardly ofsaid frame from each of said side bars, the angle iron bars extendingfrom one side bar overlapping and slidably engaging the angle iron barsextending from the other side bar to permit varying the width of theframe, said angle iron bars being of inverted V-shape in cross-sectionto discourage cows from standing thereon.
